A mobile terminal, and an information providing method and system which immediately provides information, which the user of the mobile terminal desires, for the mobile terminal. Area and related service information are stored in corresponding relationship in a database. An information server which includes means for calculating the area of the destination of the mobile terminal loads information on the destination area from the database to the mobile terminal which moves toward the destination area, using radio communication means before the mobile terminal arrives at the destination area.

摘要:
A radio LAN system based on a frequency hopping control scheme in which a deviation between frequency hopping timing in a cell and frequency hopping timing in another cell is measured, and as the deviation increases close to such a degree that causes interference, a frequency hopping pattern currently used in the cell is replaced with another frequency hopping pattern, or the order on the frequency hopping pattern is changed to avoid interference between the cells.

Data is compressed/encrypted for communication between application programs without addition of any modification to the application programs. In a communication system where a plurality of personal computers are connected to each other using communication lines, a personal computer is provided with a communication program and an application program, the application program uses a command offered by the communication program for transmission and reception of data with another personal computer, a hooking program for discriminating the command related to the data communication issued by the application program is provided and, after the hooking program has compressed or encrypted the data of application program depending on a type of the command, the command is transferred to the communication program.
摘要:
An information processing system continues communication without affecting the operation of an application when a communication line is disconnected due to a communication error. When the application sends a communication connection request to another system, an MS Manager portion connects the application via a communication line. An MS portion sends a control handle, instead of a communication line handle, to the application. When the application sends data, the MS portion changes the control handle appended to the data to the handle of the actual communication line. When data is received from another system, the MS portion changes the handle of the actual communication line to the control handle and passes the control handle to the application. When the communication line is disconnected due to an error, the MS Manager portion connects the application to the other system via another communication line. The MS portion re-sends data not yet received by the other system if there are any.

摘要:
A starter driving semiconductor switch apparatus energizes and de-energizes a starter according to a command from an outside. A series circuit to which semiconductor switches are connected in series is provided between a battery serving as a power supply and the starter. The starter is energized by bringing all the semiconductor switches into conduction. A voltage or a current at a predetermined point in the series circuit is monitored to make a self-diagnosis on whether the starter is allowed to start and whether there is a failure in the semiconductor switches according to a monitor output. The starter driving semiconductor switch apparatus is thus expected to have a longer useful life by energizing the starter not by using mechanical contacts but by using semiconductor switches.
